• Visual Studio 2008 (Pre-release) SolidBrush and Resource Dictionaries

  How can i modify the color proprety of a brush from a resource dictionary. Hew i get it and want to change the color it throws me an exception saying that the object is read-only is sield. Any workaround SolidColorBrush backBrush = this.Resources["BackgroundButtonBrush"] as SolidColorBrush; backBrush.Color = Colors.Black; Exception: Cannot set a property on object '#FFA9A9A9' because it is in a read-only state.     ResourceDictionary is not a real only collection, so my guess is that your SolidColorBrush is probably in the frozen state before you setting value on it, actually when you call Freeze() method on a brush, you cannot change it later on. edit: another reason why you got ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Coordinate system and matrix inconsitencies

  I still don't understand the intent of not using DirectX's left handed coordinate system. I thought it made sence at first, since OpenGL uses a right handed coordinate system.It would open up for easier porting of OpenGL code and interop integration with OpenGL libraries. Now I would prefer to have things the same way as DirectX so that I can easily use libraries and code from DirectX, but that's me. I can still say that all is good and a right handed system is just fine. But then I notice that matrices in XNA use row major representation, just like DirectX and not like OpenGL's column major matrices. Now it is only a matter of the order you multiply your matrices in and it really doesn't matter which one you use as long as you know whi ...Show All

• Visual C++ Dynamic COM DLL Referencing Question

  Forgive me if this is a very trivial process. I'm not a C++ programmer but do need to research how something might be done in C++. How would an C++ application dynamically create a reference to an ActiveX control inside of a function Here's a rundown on what we're trying to do. We develop custom CAD applications on top of OLE capable CAD engines such as AutoCAD. This allows us to take control of the CAD engine and perform drawing operations, reading data off the drawing, etc. The only problem is the HUGE bottleneck in speed by using OLE Automation. Some other CAD engines give developers the capability of using DLL's instead of writing a seperate app and controlling the CAD app with OLE. It gives a big performance boost. Unfortunetely, ...Show All

• Visual Studio Team System Label history

  How does one obtain history and properties of an existing label Especially from GUI. Thanks, Maggie Hello, label is a list of files and its versions (it does not need to be one point in time) so properties and history can be a little confusing. What information exactly do you need As somebody mentioned File->Source Control->Label->Find Label let you list content of the label. I believe History Sidekick ( http://www.attrice.info/cm/tfs/index.htm ) has some functionality that you are interested in. ...Show All

• Visual Studio Express Editions Excel Macro question

  I have a Macro built in excel and at the end of the macro, I want it to move the selected cell down one row. For example, the macro performs its function, then I need it to move down one row to set itself for performing the macro again. I tried using the down arrow key in the macro recorder and that did not work. Thanks These forums are for VB.NET questions.   If your using the VB within Excel then this is VBA (Visual Basic for Applications) which the macro record is generating code for then this is a very different product from VB.NET and there are some other locations where you will get a quicker and better response to your VBA questions. You may find more assistance in following w ...Show All

• Visual Studio Team System Unclickable modal dialog box

  Occationally when attempting a check in to TFS I run into the following error: Error There is no working folder mapping for C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\... This has only started recently and the result is that a modal dialog box immediately pop under Visual Studio, unseen . VS then gets stuck in the check in phase with no way out. Atempting to close VS gives me this message: Microsoft Visual Studio cannot shut down because a modal dialog is active. Close the active dialog and try again. I am able to see a modal box (displaying the error above) but it is unselectable and unclickable . The only way to get out of it is to force quit VS in Task Manager.

• .NET Development Listening to Caller ID sent by remote computer (C#)

  Hi. I have a VoIP modem and I connect it to my family's computer. The program that I use which serves as a server is YAC (Yet Another Caller ID) . In my laptop, since I used Ethereal to listen to the caller ID info, here's an example text: ..k..h.....`..E..I9d@... ..........|).....Ey.YP.......@CALLYAC Test Call ~(425) 555-1212 As I can tell by looking at the hex editor and packet information, the MAC Destination are associated with "..K..h", the source are associated with ".....`", a type (IP) with 0x0800 which is associated with "..", next is Internet Protocol (E..I9d@.. .........), Transmission Control Protocol that contains source port, destination port, seq, ack, and len (don't know what seq and ack ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Sprite Blitting question - Wondering if this is still a problem

  Hi all, When Beta 1 was out I dove right in and started working on a simple demo that moved a sprite with some alpha transparancy around the screen. The way I had it set up was something like this: -I had a class set up for the sprite that I called Player -The Player had a Vector2 for his screen position. -If the user was pushing the left thumbstick in any direction, the Player class's move function was called ,where a new X and Y location was made based on the angle that the thumbstick was pointing. -When Drawing the sprite, I'd get the sprite's screen position vector via a get property. Doing it this way often made my screen position vector have decimal values for the X and Y screen position of my Player sprite. This caused some funky is ...Show All

• .NET Development How do I know what framework I need?

  I have Windows XP Windows Media Center and .NET Framework 1.1 Configuration (version 1.1.4322.573). I see downloads for 2.0, 3.0. Do I need these and how do I know well you dont need them unless some software requires it. you can stick with the one you have, its actually bundled into the SP2 I believe of Windows XP (all versions) you can always stick with the latest and greatest have .NET 3.0 is still not fully complete, so you can use .NET 2.0 if you like. If you are developing applications in VS.NET then the appropriate .NET Framework will be installed however you are more or less stuck with the .NET Framework version to develop in by VS.NET VS.NET 2002 -> .NET 1.0 VS.NET 2003 -&g ...Show All

• Visual C# Can anyone give me an answer to this?

  Your program will be fed 800 distinct numbers from of a range of 8001 to 9000. You need to store these in-memory and then print. How would you do it Thinking of an array of ints Well, that would need around (4 x 800 = 3200) bytes. Can you reduce the required memory further (by more than 20 times) Regards Mani Thanks for the answer Anomolous There is a bitarray class which does the job cleanly By the way, I could also have boolean array if system stores bool as bits. Does bool take one bit Regards Mani ...Show All

• Visual Studio 2008 (Pre-release) Xbap and standalone applications in Vista.

  I came across some errors while developing wpf applications in vista. So I have a couple of questions. I would appreciate anybody who makes an effort to go through them and answer. I have tried to document what I tried in some detail. Question 1 I created an xbap (formerly known as WBA) application using a standard template provided in VS 2005.Hit F5 to start application with debugging, so my xbap application launches within IE. This is the expected behaviour. Until this point everything looks good. Go to the bin\debug inside my project directory and double click on the xbap application there. I get an error message. Well this no the expected behaviour. "Application cannot be downloaded. Check for network connectivi ...Show All

  I am unsure how I can use an application I have created on another computer that does not have vb or .net installed on it. I am using the express edition. smithju@gmail.com.(donotspam ) thanks you need to install .NET Framework 2.0 on the computers you wish to run your app. if you do not, then your app will not run.

• Software Development for Windows Vista Both Client and Server Hosted Workflows in Single Tracking Store

  We are creating a new application and would like to use Workflow Foundation as a fundamental aspect. We know we want to use server based workflows and we are considering client based workflows as well. We envision client based workflows primarily for managing UI aspects such screens to be displayed, as we don't want to manage this from the server due to lag times. My question has to do with how to have a centralized workflow management/tracking system that includes workflow instance information from all clients as well as the server based workflows. We foresee the need to reassign client workflows or to monitor abnormally terminated client workflows through this centralized tracking system (we would need to include persisted workflows as w ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotate and translate

  It must be late or something because I can't get something pretty trivial to work. I'm getting input from the XBox controller...specifically the right joystick. Any Y movement is supposed to make my model move along the Z axis. Any X movement causes the model to rotate around the Y axis. Simple enough. When I move the joystick directly forward the model moves...if I move the joystick directly to the side the model rotates. When I move the joystick diagonally thus getting input from both the X and the Y axis the model does not both translate and rotate. It doesn't do much of anything. Heres my code.... if (state.ThumbSticks.Right.Y != 0) { Vector3 newPosition = new Vector3 (); newPosition.X = hm.Model.Bones[ " ...Show All

• SQL Server Reusability & SSIS - issues they do not write in books about

  I have a simple requirement: Each package needs to have Error Handling - which needs to Execute a SQL statement. It's the same Stored Proc - where each package passes in its ID. Ok - I get that part about creating a custom task and so on for reusabilty. But - lets say that after deploying this task in 20 packages - I need to change the name of the Stored Proc. What is going to happen in that case Correct me if I'm wrong - but after deploying the new version of the custom task - do I need to go to each package and update the reference to new version Jon Limjap wrote: I think for what you want to do you have to save your script in a legitimate VB 2005 class library and register that class library with the CLR so you can referenc ...Show All
